After considerable development time and testing Gintani has released their Stage I supercharger kit for 5.0 liter S85 V10 equipped vehicles such as the E60 M5. Stage I delivers 6.5-7.0 psi of boost from a Vortech blower (self-contained oil) good for gains on the Gintani Dyno Dynamics of 165 wheel horsepower over the baselnie. Keep in mind the Dyno Dynamics reads lower than a Dynojet so the peak figure of 530.4 wheel horsepower would likely rise to around ~600 wheel range on a dynojet.

The entire kit consists of the Vortech supercharger, supercharger bracket, pulleys, belts, carbon intake, air filter, air to water cooled intake manifold, air to water aftercooler, water reservoir, spark plugs, fuel injectors, external water pump, blow off valve, and hoses. The price for all of this is $14,995 but the first 5 kits are $13,500 with a free install.

Lol, it's not rediculous if you compare it to another rediculously-priced BMW supercharger kits! $15k for a SC kit is insane.

A KB blower kit for the 5.0 is $7k and makes 800whp and 140mph traps (Boss 302).

The performance is great of the above M5 kit, but it is par for course in pricing. $15k? Lol

There are a lot more Mustang owners who supercharge their cars, economies of scale allow Mustang tuners to recoup their R&D costs more easily than a tuner who works on the E60 M5 because there are comparatively few M5 owners who will supercharge their cars, so each kit they sell has to cost more.

Oh please. It's a custom mounting bracket and belt, it's not made out of some exotic metal or process. Just like the $3k+ exhaust systems, it's got a BMW tax.

The price and power for the 5.0 supercharger kit is legit. That motor is extremely impressive and makes outstanding power out of the box. They only charge $15k for supercharger kits on BMWs because people out there will pay for it.
